Library Versions
implementation("io.github.Rosemoe.sora-editor:editor:0.22.2")
implementation("io.github.Rosemoe.sora-editor:language-textmate:0.22.2")
It's an unresolved bug in the editor, and it happens due to the reason below.
The editor inserts the unicode char from platform API KeyEvent#getUnicodeChar directly.
According to the bad code point value and javadoc of getUnicodeChar, 0x800002C6 is a masked code point which indicates this key needs special treatment to actually produce a character. And the masked code point is invalid, so the exception is thrown. After removing the mask, the code point represents U+02C6, which is a modifier letter for circumflex accent.
From Android docs:
If the return value has bit KeyCharacterMap.COMBINING_ACCENT set, the key is a "dead key" that should be combined with another to actually produce a character -- see KeyCharacterMap.getDeadChar -- after masking with KeyCharacterMap.COMBINING_ACCENT_MASK.
From Android source code:
public static final int COMBINING_ACCENT = 0x80000000
Before version 0.23.2, the editor transforms the result getUnicodeChar directly into a char array by Character#toChars and insert it.
In version 0.23.2 the editor avoids to insert private-use Unicode characters for Android framework, but still, does not handle the masked code points.
I'll fix the bug soon.
